scope:

This document provides guidance on taking and handling samples that are collected as part of an investigation into the likely source of a crude oil or petroleum product spill into a marine or aquatic environment. Guidance is given on taking samples from both the spill and its potential source.

Mostly, oil sampling is part of legal procedures and has to be treated like any other preservation of evidence (legal sampling).

WARNING - Taking samples may involve hazardous materials, operations and equipment.

This document is not intended to address all the safety and health aspects associated with the guidance given. It is the responsibility of the user to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

IMPORTANT - Most countries have special trained teams to take samples on board of ships. As police officer or law enforcer, don't take unnecessary risks and ask assistance from such a team when available.

NOTE For the sake of clarity, the word 'oil' is used throughout this document. It can equally refer to crude oil, a petroleum product or mixtures of such.
